The invention relates to improvements in with an out turned ange 5. A nozzle 6 is exhaust steam spreaders and particularly to also supplied, the nozzle being in the form an exhaust steam spreader for use on the nozof a ring inserted in the upper end of the zle stand of a locomotive and an object of nozzle stand and having an upwardly conthe invention is to provide a device which verging inner wall T and provided with an 5o can be readily mounted on the upper end of out-standing flange 8 resting on the flange 5'. the nozzle stand and will operate to spread The nozzle is fastened to the no-zzle stand by exhaust steam as it passes upwardly to the a plurality of suitably spaced bolts 9 which smoke stack and to distribute the steam even* pass through the flange 8 and screw thread 10 ly over the entire cross sectional area of the into the flange 5. 55`- stack, such insuring of the effective discharge The above parts are as customarily proof the products of combustion from the smo-ke vided on locomotive boilers and form no part box through the stack. of the present invention and in vthis connec- A further object of the invention is 'to tion, it might be remarked that the exhaust provide a, spreader of simple design and of steam passing up through the nozzle stand 6o inexpensive construction and which can be. is directed through the nozzle into the lower placed on existing nozzle stands without reend of the smoke stack and is utilized to clear quiring any alteration in the structure therethe products of combustion from the smoke of and also which can be mounted on the bOX.

According to this 535-' The smoke stack 1 extends upwardly from arrangement, it is only necessary to remove the smoke box 2 and has the lower end there the existing bolts which fasten the nozzle to of out flared as indicated at 8 and lying dithe nozzle stand, put my spreader in place rectly above the upper end ofthe conventionand fasten the same to the latter parts by t al nozzle stand 4 which latter is provided utilizing the bolts 9 herein shown. 90

It will be particularly observed that thev bottom or contracted end of the outer ring 10 of the spreader has an external diameter somewhat less than the internal diameter of 5 the upper end of the nozzle opening so that a certain amount of up going steam is passed between the annular opening appearingbe- `tween the nozzle and vthe lower end of the ring and is spread outwardly and upwardly by 10 the outer face of the ring 10 into the'lower end of the stack.

' Further it will be observed that a certain proportion of the up going steam will be passed between the rings 10 and 12 and will A be defiectedupwardly and outwardly thereby and that a certain proportion of the'up going steam will be passed through thek center of the ring 12. By properly positioning the rings of the spreader in regard tothe upperl end of the nozzle and flaring the rings 1() and 12 a proper amount, I am able to spread the vup 'going exhaust'stea-in so that it is distributed evenly over the entire cross sectionalV Y area of the lower end of the stack and by so doing, insure of the effective clearance of the i products of combustion from the-smoke box through the stack. l

' It will be particularly observed that this device can be installed on existing locomotives without requiring to alter any-existing structure and that it in no way interferes with the nozzleand permits of the ready changing o the nozzle as and when required. l Y
